NOTTINGHAM, England – Dana White thought he had Daniel Cormier’s next opponent all set up. Instead, it was back to the drawing board.

Cormier (10-0 MMA, 7-0 SF) was scheduled to fight former UFC heavyweight champ Frank Mir (16-6 MMA, 14-6 UFC) in about a month in Oklahoma City. But Mir dropped out with an injury, and White and the Zuffa brass went to work on his replacement.

White thought it was going to be Matt Mitrione (5-1 MMA, 5-1 UFC) – but the UFC heavyweight turned down the fight earlier this week.

“He wants to fight a guy who weighs 205, but doesn’t want to fight the guy who’s the real heavyweight, the legitimate guy who’s ranked. And Mitrione’s not getting any younger.”

The 205-pounder White alluded to is Quinton “Rampage” Jackson, who has a newly developed beef with Mitrione, the popular Season 10 contestant from “The Ultimate Fighter” who had an NFL career before jumping into MMA.

But White said a Mitrione-Jackson fight isn’t in the cards. Jackson is a light heavyweight, but could move up, of course. But he’s also on the shelf after pulling out of a UFC 153 fight against Glover Teixeira.

Now White and Co. will get back to work looking for who “anybody” will be next.

Strikeforce’s Oklahoma City show is scheduled for Nov. 3 at Chesapeake Energy Center. Cormier, a former standout wrestler at nearby Oklahoma State University, is slated to headline the Showtime-televised main card following prelims on Showtime Extreme.
